The SHIROKAI kit itself fits without weeks of sanding or trimming and arrives ready for paint or wrap. Body prep (cutting the arches, drilling for rivnuts) is a standard part of every widebody install, on any car and with any widebody kit.
Below: the SHIROKAI kits we have in stock, fitment by trim in the same wording as the product pages, and current prices from the store.
Kit fit vs body prep
People mix up two different things when they ask whether a widebody kit "fits without modification".
- Kit fit: how the parts sit on the car. Our panels are CNC-cut from 3D scans of the factory body, so they go on without weeks of sanding or trimming and arrive ready for paint or wrap.
- Body prep: what is done to the car. The arches are cut and the fenders drilled for rivnuts on any car with any widebody kit. It is part of the process.
If you plan wide wheels, the rear arch may need additional trimming. Use the Widebody Wheel Fitment Calculator to size the wheels first.

FAQ
Does a SHIROKAI widebody kit fit without modification?
The kit itself fits without weeks of sanding or trimming and arrives ready for paint or wrap. The car still needs body prep: the arches are cut and drilled for rivnuts, which is a standard part of every widebody install. Fitment by trim is in the table above, and the notes there are copied from each product page.
Do I still have to cut and drill my car?
Yes. Cutting the arches and drilling for rivnuts is part of installing any widebody kit, ours included. The fender is drilled for rivnuts on every car wether open hardware or hidden. When you run wide wheels, the rear arch may need extra trimming. In rare cases front wheel well area may need extra attention to move some of the hidden block or parts from contacting the wheel (washer fluid tanks, electronics, oil coolers need to be moved or replaced with aftermarket alternatives to avoid damage from wheel contact)
Will the Charger kit fit a factory widebody car (Hellcat Widebody, Redeye Widebody, Scat Pack Widebody)?
Yes. It fits the factory widebody car too, with small fitting adjustments during install, nothing major. SRT Hellcat, Hellcat Redeye, SRT 392 and Scat Pack cars with the standard body are direct fit. R/T, R/T Plus, GT, SXT and SE trims need minor front bumper modifications.
Which trims are direct fit, and which need bumper work?
Trims the kit was developed for, or that share its factory front bumper (for example Charger and Challenger SRT, Mustang GT and EcoBoost, Camaro 1SS and 2SS, M4 F82 Coupe), are listed as direct fit. Trims with a different front bumper are listed as bumper check or modifications required, so test-fit the bumper endings first. The table above has the exact wording per trim.
How long does a SHIROKAI widebody install take?
A typical body shop install takes 1-3 days, excluding paint or wrap. Our kits are CNC-cut from 3D scans of the factory body, so the time goes into body prep, not into reshaping the panels.
What do the prices include, and what does shipping cost?
Prices are in USD. For the US and Canada the price includes import duties. Shipping is separate: US widebody kit shipping is $590, and taxes are calculated at checkout where required. In other countries, shipping is calculated at checkout and duties are paid on delivery.
